These are some questions that have been answered by the creators of the show Kim Possible. I collected thae ones that deal with Shego.

Q: -Mr. Loter, why is purple Shego's 'color of choice' when she's being influenced/controlled by an outside factor?
A: Purple is a good color in the KP universe. It works well with our backgrounds and character colors.

Q: -Mr. Loter, do you know where Shego's mom is? Also, do you know the birthdays of: Shego
A: Sorry, we have never thought about it.

Q: -Do you (Steve Loter) know about Shego's past? Will any of the episodes (or the movie)show us anything about it?
A: No.

Q: -Mr.Loter, how old is Shego anyway?
A: Shego is in her early 20's.

Q: 7) I've always wondered why Shego is so set against cloning. Is it because of her brothers Wego 1 and Wego 2?
A: Not necessarily. I believe that Shego thinks Drakken is a screw up and she doesn't want to be involved in any of his genetic experiments.

Q: -What is Shego's real name or is that her real name?
A: As far as we know, it's her name.

Q: -2) Has is Shego been with green skin? Has she always been like that?
A: Yes.

Q: -What is Shego's last name?
A: It's never revealed.

Q: -Is Shego's power just in her hands? If so....Why?
A: We thought they looked cool.

Q: -Why does Shego play second fiddle to Drakken when we know that she could easily take over the world without him (ASIT)?
A: I dont know if Shego really knows that. It takes the future Shego to convince the present Shego to take the Time Monkey for herself.

Q: -IF you had absolute authority in deciding a) where Shego's parents are, b) what happened in her past, including why she went evil, and c) what her last name was, what would you decide?
A: I think I'll refrain from answering this since this might be something Mark and Bob would want to explore if there was a future for KP.

Q: -Often, we see what appears to be Shego filing her nails, but her gloves are still on! It has been speculated that she is actually sharpening her gloves whith the file. Is this correct?
A: Yes, her gloves have a super sharp blades in them.

Q: -what exactly is Shego power
A: Think of it like Cyclops optic blasts in X-Men. It's bursts of force and power, not necessarily heat and flame.

Q: -How come Shego still wears her jumsuit from Team Go?
A: You make a good point, but we love that costume.

Mego:
Q: --Is Mego older or younger than Shego. How old?
A: Mego is a few years older.

Wego & Wego:
Q: -What are the Wego's individual names
A: Wego and Wego.
